LOOlVl-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 785,925, dated March28, 1905.

Application filed January 24, 1905. Serial No, 242,537.

To (LU whont it may concern.-

Be it known that I, ALFRED VV ITEHEAD, a citizen of the United States,residing at Fall River, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement inLoom-Shuttles, of which the following is a specification.

This invention has reference to an improvement in loom-shuttles, andmore particularly to an improvement in threading devices forloom-shuttles. I

The object of my invention is to provide a loom-shuttle with amechanical threading device for threading the shuttle without suction.

Further objects of my invention are to simplify the construction andreduce the cost of threading devices for loom-shuttles; and 1 accomplishthese objects by constructing the threading device of sheet metal.

My invention consists in the peculiar and novel construction of amechanical threading device for loom-shuttles, as will be more fully setforth hereinafter.

Figure l is a top plan view of the delivery end of my improvedloom-shuttle, showing the weft-thread from the bobbin in the positionfor entering the threading device in broken lines and the position thethread would assume after the thread has passed through the threadingdevice to thread the shuttle in full lines. Fig. 2 is a side view ofFig. 1, showing the thread coming from the aperture in the threadingdevice forming the delivery-eye of the shuttle. Fig. 3 is a transversesectional view through the shuttle and threading device, taken on line XX of Fig. 2. Fig. 4 is a transverse sectional view through the shuttleand threading device, taken on line Y Y of Fig. 2. Fig. 5 is a face viewof the sheet-metal blank from which the threading device is formed. Fig.6 is a rear view of the threading device formed from the blank shown inFig. 5, and Fig. 7 is an end view of the threading device.

In the drawings, (0 indicates the delivery end of a loom-shuttle; b, theend portion of a bobbin in the shuttle; c, a weft-thread, and (Z myimproved threading device. The shuttle to has the oblong cavity (4',extending from the usual bobbin-cavity toward the point of the shuttleand from the top of the shuttle downward to a point slightly below thecenter line of the shuttle; the notch a in the rear side wall of thecavity a, as shown in Figs. 1 and 3; the groove a in the top of theshuttle. extending from the cavity (4 toward the point of the shuttle;the depressed portion (0 in the top of the shut-tle, shaped to receivethe fiat body of the threading device (Z; the recess a in the side ofthe shuttle, shaped to receive the deliveryeye arm of the threadingdevice; the transverse hole a, extending from the oblong cavity a to therecess a on a line with the delivery-eye of the shuttle, as shown inFig. 4c, and the slot a extending from the cavity a to the recess a andfrom the depressed portion a to the transverse hole a, as shown inbroken lines in Figs. 1 and 2. Otherwise the shuttle may have theconstruct-ion of any of the wellknown forms of loom-shuttles.

My improved threading device (Z is formed from the sheet-metal blankshown in Fig. 5 to have the flat body portion (Z, in the fixed end ofwhich is the screw-hole (Z The free end of the body portion extendstoward the point of the shuttle and is shaped to have the point (Z andthe rounded corner (Z. A tension-arm (Z is formed on the rear of theflat body portion (Z by first bending up the wings (Z (Z at right anglesto the arm, then bending the arm downward and upward to form the loop (Zand then outward to form the upwardly-curved end (Z as shown in Figs. 3,6, and 7, and a delivery-eye arm (Z is formed on the front of the flatbody portion by bending the arm downward at right angles, as shown inFigs. 4 and 7 This arm has the aperture (Z in the end forming thedelivery-eye of the shuttle, and the slot cl ,extending from theaperture downward through the end of the arm, as shown in Figs. 2 and 6.

The threading device (Z is placed on the depressed portion (0 of theshuttle in a position for the tension-arm (Z to extend downward into thecavity a, the curved end (Z entering the notch a in the rear side wallof the cavity, and the delivery-eye arm (Z to extend downward in therecess a in the side of the shuttle, and the whole secured by the screw(Z through the screw-hole (Z as shown in Fig. 1. With the thread-guidesecured in its operative position, a space a is formed between the freeend of the thread-guide and the wall formed by the depressed portion a,a space is formed between the under side of the free .end of the threadguide and the depressed portion a", and a space 9 is formed between theedge of the delivery-eye arm d and the right hand edge of the recess a,as shown in Figs. 1 and 2, for the entrance of the weft-thread a. 1n theoperation of my improved threading device for loon'i-shuttles the thread0 is carried by hand through the cavity (6 and the groove (0 as shown inbroken lines in Fig. 1, thus bringing the thread in a position to enterthe tension-arm cl". The thread is now caught under the rounded corner(Z of the threading device, which brings it into the space 0, then underthe point (Z of the threading device, through the space f, down throughthe slot a in the shuttle and the space g, and up through the slot (Zinto the aperture (Z forming the delivery-eye of the shuttle when theshuttle is threaded. The thread now comes from the bobbin I) through thecavity a, over the wings d d and between the loop (Z of the tension armd through the transverse hole a in the shuttle, and out through theaperture (Z10, forming the delivery-eye of the shuttle.

By the use of my improved threading device on loom-shuttles the shuttleis quickly and positively threaded without suction and a more durableand inexpensive threading device is provided than has heretofore beendone.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a loom-shuttle, a threading device formed fromsheet metal to have a flat body portion, a tension-arm, anda'delivery-eye arm all formed integral, a shuttle having a depressedportion for the body, a cavity for the tension-arm, and a recess for thedeliveryeye arm of the threading device, and means for securing thethreading device to the shut tle, as described.

2. In a loom-shuttle, a threading device (Z formed from sheet metal tohave the flat body portion (Z, the screw-hole (Z the pointed end d, therounded corner cl, the tension-arm (Z having the Wings d cl, the loop (Zand the curved end (Z and the delivery-eye arm (Z having the aperture (Zand the slot (Z all formed integral, as described.

3. The combination with a loom-shuttle (0 having the cavity a, the notch(6 in the side wall of the cavity, the groove (5", the depressed portiona, the recess a", the transverse hole a, and the slot (0 of a threadingdevice (Z having the flat body portion d, the screw-hole (Z the pointedend (Z the rounded corner (1*, the tension-arm (Z having the wings d (Zthe loop (Z and the curved end (Z and the delivery-eye arm (Z having theaperture (Z and the slot (1" all formed integral from sheet metal, theshuttle and threading device being shaped to form the space (1, thespace f, and the space g for the entrance of a weft or lilling thread,and means for securing the threading device (Z to the shuttle (4consisting of the screw cl, as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALFRED \VHITEHEAD.
